Browse code PSCI: Invoke PM hooks only for the highest level This patch optimizes the invocation of the platform power management hooks for ON, OFF and SUSPEND such that they are called only for the highest affinity level which will be powered off/on. Earlier, the hooks were being invoked for all the intermediate levels as well. This patch requires that the platforms migrate to the new semantics of the PM hooks. It also removes the `state` parameter from the pm hooks as the `afflvl` parameter now indicates the highest affinity level for which power management operations are required.

This patch optimizes the invocation of the platform power management hooks for
ON, OFF and SUSPEND such that they are called only for the highest affinity
level which will be powered off/on. Earlier, the hooks were being invoked for
all the intermediate levels as well.

This patch requires that the platforms migrate to the new semantics of the PM
hooks. It also removes the `state` parameter from the pm hooks as the `afflvl`
parameter now indicates the highest affinity level for which power management
operations are required.
